That day, in the late morning hours, Theresa and Sam Schulte, her companion, were in the back seat of an SUV driven by Tour Guide, Leon Rodriguez (some have reported that the driver’s name is Leon Garcia of Big John’s Tours.) Before noon, Rodriguez overtook an 18-wheeler that was transporting oranges, and several seconds later returned in the same right lane. At this point, there are different witness accounts, mainly from Rodriguez, and the driver of the truck, Miguel Angel Arriaga. Rodriguez told the authorities that he slowed down to make a right turn, while Arriaga said that Rodriguez came to a complete stop in the middle of the road, with no turn signal indicating he was going to make a right. Arriaga told Police that he was unable to stop the truck in time and he rammed the 18-wheeler into the rear of the SUV at great speed.

Theresa and Sam were both stuck in the completely destroyed SUV for almost one full hour before an ambulance arrived at the scene of the accident. They were both taken to the hospital, but Theresa did not survive her injuries and was pronounced dead at the hospital later that day.
